A damaged barcode does not have to stop your work. WareCode reads visible numbers and text from a photo and turns matching values into clean barcodes you can use again. RECOVER CODES FROM DAMAGED LABELS When the barcode is scratched, faded or torn but its printed digits are still readable, take a photo or choose one from your library. WareCode recognizes the text, extracts matching codes and lets you display a clean barcode. You can also enter the value manually. SCAN BARCODES AND QR CODES Use the camera for everyday QR codes and barcodes, or recognize codes from an image. Review recognized results and choose what to use or save. Keep useful values close at hand in your saved list. SAVE LINKS AND SHARE QR CODES Store useful links alongside your other codes. Turn a link or text into a QR code to share it from your screen, and switch between barcode and QR display when needed. RECOGNITION THAT FITS YOUR WORK Use built-in recognition patterns or add your own rules for codes and numbers in photos and recognized text. Edit patterns, enable only the ones you need and choose which matching values to save automatically. This is useful for repeated labels, reference numbers and warehouse documents. MADE FOR DAILY USE • Barcode and QR generation • Camera and photo recognition • Saved codes, links and paired values • Custom recognition patterns • Adjustable code backgrounds • Light and dark appearance • Ukrainian, Polish and English interfaces Text recognition and code generation run on your device, without an account. Opening websites and other external actions may require an internet connection. Recovery requires readable printed numbers or text in the image. WareCode cannot reconstruct missing or completely unreadable information. Recognition results should be checked before use.
